He was a leader one would have willingly followed to the end of the earth. When, therefore, he proposed that I should accompany him on an ivory trading expedition to Galla-land, that vast stretch of country lying between Mount Kenia on the south and Southern Somaliland on the north, which is nominally under the sphere of influence of the British East African Protectorate, I jumped at the chance; and it was so arranged. He had been over much of the ground we intended covering, and knew the country, so that it promised to be a most interesting trip. About this time I heard from George that he was coming down country, as the steamer parts had not all arrived from England, and consequently it would probably be months before it would be ready for building. He had also had a bad attack of malarial fever in the unhealthy district immediately surrounding the lake at Ugowe Bay, and altogether he was not very fit. I suggested to El Hakim that George should join us in our proposed expedition, to which he readily agreed; so I wrote to George to that effect. To render the prospect still more inviting, there existed a certain element of mystery with regard to the river Waso Nyiro (pronounced Wasso Nēro). It has always been supposed to rise in the Aberdare Range, but, as I shall show, I have very good reason to believe that it rises in the western slopes of Kenia Mountain itself. The Waso Nyiro does not empty itself into the sea, but ends in a swamp called Lorian, the position of which was supposed to have been fixed by an exploring party in 1893. But, as I shall also show in the course of this narrative, the position of Lorian varies. The upper reaches of the Waso Nyiro were visited by the explorer Joseph Thompson, F.R.G.S., on his way to Lake Baringo during his memorable journey through Masai Land in 1885. In 1887-1888 a Hungarian nobleman, Count Samuel Teleki von Czeck, accompanied by Lieutenant Ludwig von Hohnel, of the Imperial Austrian Navy, undertook the stupendous journey which resulted in the discovery of Lakes Rudolph and Stephanie. Count Teleki, on his journey north, crossed the Waso Nyiro at a point in North-West Kenia near its source, while Lieutenant von Hohnel went two or three days’ march still further down-stream. A few years later, in 1892-1893, Professor J. W. Gregory, D.Sc., of the Natural History Museum, South Kensington, made, single-handed, a remarkable journey to Lake Baringo and Mount Kenia, and in the teeth of almost insuperable difficulties, ascended the western face of that mountain and climbed the peak.
